Be it known'that-I, DImuK vUnited Mason, in the State 'of Nevada,

States of America, have invented certain new and useful Improvements in Water- Cooling Systemsifor Internal-Combustion Motors, of which the following is a'specification.

invention is applicable particularly to motor cars operating under conditions in which the' ordinary water cooling system is inadequate;

cooling system becomes too hot and boils'away necessitating stops to allow the motor to, cool ofl. and for replenishing the water supply, andmy object is to devise means for in crea'singwhenever necessary the volume of cooling water in communication with the cooling system and for automatically replenishing the water in'the radiatorof the coolingsystem to keep the water level at; '25 the-height necessary for effective circulation.

I attain my'object by means of the constructions-hereinafter described and illustrated inthe accompanying drawings in I water cooling system on a larger scale.

In the drawings'hke numerals of reference indicate, corresponding parts in the difi'erent 13 is an internal combustion motor of which6 is .the inlet water connection of its water jacket and 7 the outlet connection,

these being connected to the top and :bottom respectively of the radiator 5 of ordinary Ireferably .in front of the upper part of the radiator 5 I locate a' tank 1 which preferably does not extend up above the top of the 'upper'part of the radiatorfi. This tank is i preferably closed by acap 2 similar to the vemence is connected an. operating rod. 12,

cap 14 of'theradiator'5. The bottom of the tank'l'is'connected by means of a pipe 3 50 with the bottom of the radiator 5. In this pipe is located a .valve4 to which for conthe rear end of .WhICh iS located in any'con of the motor car from his seat.

the radiator 5. The preferredarrangement-- is to employ a pipe9 leading, from the upper part of the tank pasing below the lower part of the radiator'5 and connected to the lower end of the usual overflow pipe 8 leading from the. upper part ofthe top of the radiator 5. overflow is provided for the tank 1, this being preferably a pipe 11 arranged as is common in ordinary radiators.

When the motor-is cold, the cooling sys- I UN'TED STATES 7P -TBNTIOFFICEQ1.

tem may be filled through either of the caps 2 or 14. -Under normal conditions when overheating is not likely to occur, the valve- 4 'is closed,'and the device operates in the ordinary manner. Assuming that overheatmg is occurring or is likely to occur, the

valve 4: is opened, the lower 'part of theradiator 5 is immediately placed in communication witha considerable body of cool water gravity.

contained in thetank 1, which by tends to flow into the radiator 5 and displaces the hot-water therein, which flowsthrough the pipes 8 and 9 to the upper part ofthetank1.'-

I find inpractice that owing to the greater weight of the cold water, the flow of water from the tank 1 to the radiator will occur even when the water level in the tankisconsiderably below the water level in the 'radia.- tor, consequently thewater from the tank will flow readily to the radiator 5 when t e.

water in thelatter is and only steam is passing through the pipes9 and 10; The pipe 11 permits of the free escape of steam generated and serves also'as an overflow for any surplus water due to" expansion or to overfilling- I find that-my improved cooling system will work with complete satisfaction, maintaining the-cooling system at a proper temperature' andkeeping it filled under conditions previously this was impossible.

' What I claim asmy invention-is:

-1. :The combination with the radiator of the cooling system of an intcrnalcombustion motor of a tank located above the level of the bottom-of the radiator; a water connection between the bottom of thetank and the bottom .of the radiator; and an overflow pipe leading from the top of, the radiator to the milk;

tion motors constructedas set forth in claim 1 in which the overflow pipe passes-below of theradiator.

A cooling system for internal combus tor of the cooling system of an internal combustion motor of a closed tank located above the level'of the bottom of the radiator; a water connection between the bottom of the tank and the bottom of the radiator; a control valve in said water connection; an overflow pipe leading from the top of the radiator to the tank; and an overflow outlet from the tank.

4. The combination with the radiator of the cooling system of an internal combustion motor of a tank having a high water level approximately the same as that oft-he radiator and having water connections with both the top and bottom of the radiator.
